Majed Moqed, 24, is possibly a Saudi national, according to the FBI. He and the other four hijackers of Flight 77 worked out at Gold's Gym in Greenbelt, Md., between Sept. 2 and Sept. 6. The men purchased weeklong memberships, according to Gene LaMott, president and CEO of the workout chain. Moqed also was seen in two stores in Maryland's Washington suburbs looking over adult videos and books, although employees say he made no purchases. Moqed was one of five hijackers who went to the Arlington County, Va., Department of Motor Vehicles on Aug. 2 seeking state identity cards.
